Let $e(n)$ be the number of $n$-element order ideals in a hexagonal lattice. We give the enumeration of $e(n)$ by showing a bijection between the order ideals and Schroder paths. Further, we get formulae for the flag $f$- and $h$-vectors of the hexagonal lattice....

you put 2 floquet conditions for each pair of opposing boundaries. When defining your unit cell, make sure your boundaries are either along y or x direction. This makes it easier to define kx and ky vectors. Plasmonic wire grating explains implementation of floquets in detail ...
The multicomponent density waves corresponding to the commensurate M-point ordering vectors are worked out in detail. To show that our results generally apply to 2D hexagonal lattices, we develop a general low-energy SU(3) theory of (spinless) saddle-point electrons. 展开 ...
